Pixen is the best program for the pixel artist using Mac OS X. There is no competition, not even from the huge companies with several-hundred-dollar software suites. Their applications are inferior for pixel art, by virtue of their being conceived with a completely different intent.
Pixen is specifically for small-scale or pixel art; it shines better there than any other application. Not only that, but Pixen carries no price tag: it's open source under the MIT license and absolutely free.
Pixen has more unique and powerful features for pixel art than any other program, including some features that are exclusive to Pixen and have never been in any other graphics program.
The majority of these most interesting features have come as direct requests from our users, professional and amateur pixel artists who, like us, see Pixen as a tool built for the artist-not for a marketing department.
